SKYLIGHT.

Application filed November 22, 1921. Serial No. 516,924.

sky-lights and other structures having glass or similar transparent sections. Such structure may, however, be used for other purstructure "for the purpose intended which may be easily and quickly assembled,- which offers substantially no obstruction to the flow of water therefrom, which is watertight and which will compensate for expansion and contraction due to changes in teinperature.

In the accompanying drawings F l is a perspective view of the preferred embodn ment of the invention showing some of the roof sections disposed in place, and with some of the sections removed to disclose the underlying structure; Fig. 2 a transverse sectional view taken on the line HII oi Fig. 1; Fig. 3 a detail plan view of one of the transverse binding strips; Fig. 4a section taken on the linesIV-IV of Figs. 1 and 3. i 4

The structure consists of the main longitudinal supporting bars 1,transverse binding strips 2 bridging the space between them, and the panes or root sections 3, preferably formed of glass or other transparentmaterial supportedthereby.

The bars 1 are preferably made of stand-- ard rolled sections T-shaped in cross sec tion as clearly shown in Fig. 2, and are provided with the vertical web 4L and the lateral seat portions 5. The transverse binding strips are also of inverted T-shape in cross section, as shown in Fig. 4c. These strips are provided with oppositely disposed grooves 6 and 7 formed by slitting its central web 8 at intervals and bending the tongue portions 9 intermediate thereof in opposite directions so asto encase the edges of the adjacent panes or root sections 3, as clearly shown in Fig. 1. I V

Resting upon said portions 5 and filling the space between the base portions of the transverse strips are sealing strips 10 made of any suitable material, said strips being. of substantially the same thickness as the base portions of the transverse strips, so as to act in conjunction therewith to provide a fiat surface upon which the sections?) are supported. 1

In building up the structure, the sealing strips 10 are first placed upon the seat portions 5, after which one edge ofa pane or section 3 is positioned against the transverse member 9, so that the tongues 9 will embrace the edge thereof with another transverse stripabutting its opposite edge, and the several sections are similarly positioned against a previously positioned section until the en tire structure is completed. An impervious yielding compound, such as bituminous cement, is then poured around the edges of the sections so as to completely. fill the crevices between the'several parts. The tongue portions 9 of the transverse strips encase the edges of sections 8 and hold them in assembled relation. Wedges 11 are driven through apertures 12 located in the web a, which effectively lock-the transverse strips 2 and sections 3 positively in place.

The webs 41; extend but a slight distance above the surface of the sections3 and thetongues 9 lie inclose contact therewith so that substantially no obstructions are presented to hinder the flow of, water off the structure. By using a yielding compound for the sealing medium, as above described, not only a water-tight structure is secured but onewhich will compensate. for changes due to expansion and contraction caused by variations in temperature.

It is thus seen that the invention provides a simple, sturdy, inexpensive and efficient structure for the. purpose intended, and although the same is described and illustrated as embodied in a sky-light construc- I tion it is obvious that the same may be readily employed for structures intended for various uses of a-similar nature.
